BOOK-CLAMP.

SPECIFICATION forming part of Letters Patent No. 770,669, datedSeptember 20, 1904.

Application filed February 1, 1904. Serial No. 191,472. (No model.)

T 0 all whom, it nuty concern:

Be it known that I, J AMES NEELY BOSTICK, a citizen of the UnitedStates, and a resident of Fresno, in the county of Fresno and State ofCalifornia, have invented certain new and useful Improvements inBook-Clamps, of which the following is a specification. v

The invention relates, more definitely stated, to novel means wherebyloose leaves may be held and bound into book form by stapling or othersecuring means.

Specifically stated, the invention consists of a peculiar spring-actingclamp adapted to be secured upon the top of a table or other support andmeans for working it, all as will hereinafter be fully described and thenovel features pointed out in the claims.

In the following description reference is had to the accompanyingdrawings, in which Figure 1 is a perspective view illustrating myinvention in use. Fig. 2 isan enlarged detail perspective view of theclamping-jaws,

and Fig. 3 is a side elevation of a modified form of my invention.

In the practice of my invention I employ a clamp A, constructed of aplate bent upon itself at A, forming an upper jaw B and a lower jaw C.The plate may be formed of any material adapted to place the jaw B undertension, holding it normally elevated.

D denotes a rod or other device extending from the jaw B down throughopenings in the jaw C and the clamp-support E, which latter is shown inthe form of an ordinary table. The lower end of the rod. is suitablyconnected with a treadle or lever F, which may be located on the floorand its upper end provided with a head Gr above the jaw B.

It will be noticed that the jaw C has a series of standing pins orfingers H suitably spaced for receiving between them extensions I on thejaw B. The extensions are provided with notches or recesses J for thepurpose as will appear farther on.

In using my invention a batch or desired number of loose leaves arearranged in order, as indicated at K, and placed against the fingers H,as shown in Fig. 1. Now through the rod D simple pressure on the treadleF will draw down the jaw B to clamping action of its extensions I uponthe batch of leaves, as illustrated in Fig. 1. Upon necessary pressurebeing applied to the treadle for holding the leaves securely clamped anawl or punch L, held by one hand of the operator, may be forced throughall the leaves and withdrawn without disarrangement thereof. In theholes thus formed through the batch of leaves suitable binding -staplesmay be arranged and clenched, as will be understood. In punching theholes through a batch of leaves the notches J serve as gages for placingof the awl to insure that the holes be properly spaced and punchedadapted for receiving the securing-staples.

If desired, the clamp may be secured to its support by screws or othermeans arranged in openings M.

Obviously the clamp above described may be modified by forming it ofjaws hinged together at N and the upper jaw made yielding through meansof an interposed spring 0, substantially as shown in Fig. 3.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The hereinbefore-described book-clamp, consisting of yieldingclamping-jaws, one elevated above the other, means extending from theupper jaw to an operating-lever, standing fingers at the forward end ofthe lower jaw, and extensions at the forward end of the upper jaw,substantially as described.

2. A book-clamp, consisting of yielding clamping-jaws, one located abovethe other, a suitably-supported treadle, means connecting the upper jawand the treadle, standing fingers at the forward end of the lower jaw,extensions at the forward end of said upper jaw having spaced recesses,the standing fingers being spaced apart adapted to receive saidextensions between them, upon clamping action of the jaws, substantiallyas described.
